Absorption of calcium varies with age. During pregnancy, calcium absorption doubles. Calcium absorption occurs mostly in the jejunum. Calcium absorption is reduced in achlorhydria and uremia. The absorption of calcium depends on calcitriol and vitamin D. Food reduces the absorption of calcium carbonate by 10% to 30%. Absorption of calcium varies with age. During pregnancy, calcium absorption doubles. Calcium absorption is reduced in achlorhydria and uremia. The absorption of calcium depends on calcitriol and vitamin D. Which time frame describes when a patient will begin to experience relief from treatment with magnesium hydroxide (non systemic)? .5-6hrs Which administration point would the nurse share with Mrs. Woods in regard to magnesium hydroxide therapy? She should shake the suspension well before administration. She should take the magnesium hydroxide as often as needed throughout the day. She should take the magnesium hydroxide 15 to 30 minutes before she takes aspirin and lisinopril. She should follow administration of magnesium hydroxide with an 8-oz glass of orange juice. She should shake the suspension well before administration. Which patient parameters would a nurse ensure are assessed before a patient receives calcium carbonate? Weight Calcium levels Renal function Blood pressure (BP) Phosphate levels Calcium levels Renal function Phosphate levels Which patients would a nurse determine require cautious use or avoidance of aluminum hydroxide? A 51-year-old patient with gout A 29-year-old patient who is pregnant A 71-year-old patient with dyslipidemia A 55-year-old patient with chronic kidney disease A 29-year-old patient with hypophosphatemia A 29-year-old patient who is pregnant A 71-year-old patient with dyslipidemia A 55-year-old patient with chronic kidney disease A 29-year-old patient with hypophosphatemia Which statement by the nursing student in regard to the pharmacokinetic parameters of calcium carbonate requires further intervention? "The solubility of calcium is decreased in an acidic environment." "Calcium carbonate distributes primarily into bone and teeth." "Calcium carbonate is 40% protein bound." "Excretion of calcium is mostly in the feces with some excretion in the urine." "The solubility of calcium is decreased in an acidic environment." Which statement about the classification of antacids is accurate? Magnesium hydroxide is a systemic antacid that can cause diarrhea. Aluminum hydroxide is a non-systemic antacid that can cause constipation. Calcium carbonate is a non-systemic antacid and can lead to hypercalcemia. Sodium bicarbonate is systemically absorbed and may cause metabolic acidosis. Aluminum hydroxide is a non-systemic antacid that can cause constipation. Which time frame can a nurse expect aluminum hydroxide to reach its peak concentration? 30 minutes Which phrases accurately describe the mechanisms of action exerted by antacids? Raise gastric pH Lower pepsin activity Reduce acid secretion Neutralize stomach acidity Provide a protective barrier over an ulcer Rasie gas
